Value Collection JN9XX00300-050BX M3 Hex Nut 316 Ss Din 439B

Product Description

The VALUE COLLECTION JN9XX00300-050BX is a thin-profile metric hex nut machined from Grade 316 austenitic stainless steel, classified as A4 under ISO metric fastener grading. It is sized M3 x 0.50 with a 6H thread fit class and a right-hand thread direction, conforming to DIN 439B. The thin hex profile measures 1.80 mm in height and 5.50 mm across flats, making it well suited for low-clearance clamping applications. This nut is supplied in its bright, uncoated finish and is ordered in a minimum quantity of 50 units. It is typically installed by mechanical contractors, maintenance technicians, and precision assembly tradespeople working with metric fastener systems.

This nut is designed for metric threaded assemblies requiring corrosion-resistant hardware. Grade 316 stainless steel provides improved chloride and chemical resistance compared to Grade 304, making this nut appropriate for marine, coastal, chemical-processing, and outdoor industrial environments. The thin hex profile is particularly useful where standard nut height would create clearance conflicts or where weight savings are a consideration in the assembly design. It threads onto M3 x 0.50 pitch bolts and studs in both residential and light commercial mechanical applications.

Key Features

• Grade 316 austenitic stainless steel construction for strong corrosion and chemical resistance
• Thin hex profile at 1.80 mm height for low-clearance installation scenarios
• M3 x 0.50 metric thread with 6H fit class for consistent thread engagement tolerance
• Right-hand thread direction per DIN 439B standard
• Bright, uncoated finish suitable for further passivation or use as-delivered
• Supplied in multiples of 50 units to support production and service quantity needs

Compatibility

Designed as an OEM-style replacement or service fastener for any metric threaded assembly using M3 x 0.50 pitch bolts or studs requiring a thin-profile hex nut per DIN 439B.

Installation Notes

Installation is performed by hand-threading onto a clean, undamaged M3 x 0.50 threaded fastener before torquing with an appropriately sized metric hex wrench or nutdriver. De-energize and isolate any equipment before performing fastener service on live electrical or mechanical assemblies. Do not mix stainless steel nuts with carbon steel fasteners, as galvanic corrosion can accelerate material degradation in wet or corrosive environments. Consult the equipment manufacturer or applicable mechanical code for torque requirements specific to the assembly.
